Can a seal dry out if its on land?

Yes, seals can dry out if they are on land for too long. Seals have a thick layer of blubber that helps to keep them warm and insulated in the water, but this blubber can also cause them to overheat if they are exposed to the sun for too long. Additionally, seals need to stay wet in order to keep their skin from drying out. If a seal is on land for too long, its skin can start to crack and become infected, which can lead to serious health problems. For these reasons, seals typically only come onto land for short periods of time, such as to rest or to give birth.
